RGS5 Protein Deficiency Differentially Influences Blood Pressure, Vascular and Behavioral Effects in Aged Male Mice. J Cardiovasc Pharmacol 2022; 80:305-313.

Abstract
ABSTRACT Aging and elevated activity of the renin-angiotensin-system (RAS) are associated with hypertension, vascular and emotional behavioral abnormalities, like anxiety and depression. Many actions of the main effector hormone of the RAS, angiotensin II (Ang II), are mediated by Ang II type 1 receptor whose activity is modulated by the regulator of G-protein signaling 5 (RGS5) protein. We assessed the role of RGS5 on blood pressure, vascular and emotional behavioral outcomes in aged male mice in the presence and absence of chronically elevated Ang II levels. We used aged (∼21 month old) male RGS5-deficient (RGS5-/-) and wild-type (RGS5+/+) mice treated with vehicle (saline) or Ang II (1 mg/kg/d for 21 days). RGS5 deficiency increased baseline systolic blood pressure (SBP), and cerebral vascular superoxide levels in the presence of chronically elevated Ang II levels, suggesting that RGS5 deficiency leads to elevated blood pressure and deleterious cerebral vascular outcomes in aged mice. RGS5 deletion had no effect on Ang II-induced increases in SBP. Chronically elevated Ang II levels increased spontaneous locomotor activity in RGS5+/+, but not RGS5-/- mice. RGS5 deficiency and Ang II treatment had no effect on anxiety- and depression-like behavior. This is the first study to assess the effects of deficiency of an RGS protein in the vasculature or on emotional behavioral outcomes in aged mice. We report that RGS5 has protective effects on blood pressure and the cerebral vasculature in aged mice. Clinically, these data suggest that RAS blockers may significantly reduce cerebrovascular disease risk in aged males lacking RGS5.

Attenuation of nicotine-induced rewarding and antidepressant-like effects in male and female mice lacking regulator of G-protein signaling 2. Pharmacol Biochem Behav 2022; 213:173338. [PMID: 35038444 DOI: 10.1016/j.pbb.2022.173338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 01/07/2022] [Accepted: 01/10/2022] [Indexed: 11/28/2022]
Abstract
Nicotine-induced rewarding and mood altering effects contribute to the continued use of nicotine and the subsequent development of nicotine dependence. The goal of this study was to assess the role of two specific regulators of G-protein signaling (RGS) proteins namely RGS2 and RGS4 in the above described effects of nicotine. Male and female mice lacking either RGS2 (RGS2 KO) or RGS4 (RGS4 KO), and their respective wildtype (WT) littermates were used in this study. The rewarding effects of nicotine (0.5 mg/kg, base; s.c.) were assessed using the conditioned place preference model. Nicotine-induced anxiolytic-like (0.1 mg/kg, base; i.p.) and antidepressant-like (1 mg/kg, base; i.p.) effects were assessed using the elevated plus maze and tail suspension test, respectively. We also assessed effects of nicotine (0, 0.05, 0.1 & 0.5 mg/kg, base; s.c.) on spontaneous locomotor activity. Nicotine-induced rewarding and antidepressant-like effects were observed in both male and female RGS2 WT mice, but not in mice lacking RGS2 compared to respective controls. In contrast, nicotine-induced rewarding and antidepressant-like effects were observed in both male and female mice lacking RGS4 and their WT littermates. Interestingly, deletion of RGS4 facilitated antidepressant-like effect of nicotine in male, but not female mice compared to respective WT littermates. Nicotine-induced anxiolytic-like effect was not influenced by deletion of either RGS2 or RGS4, irrespective of sex. Nicotine (0.5 mg/kg) decreased locomotor activity in both WT and KO mice compared to respective saline, irrespective of genotype and sex. Taken together, these data provide evidence that RGS2, but not RGS4, plays a role in mediating the rewarding and antidepressant-like effects of nicotine. Further research is required to explore the role of RGS2 after chronic exposure to nicotine.

Abstract
Regulator of G protein signaling 2 (RGS2) is a gene involved in neuronal plasticity and synaptic signaling, whose expression in the brain is altered in neuropsychiatric and neurodegenerative disorders. Microarray data from large datasets suggested reduced RGS2 mRNA levels in the post-mortem brain tissue and blood of Alzheimer’s disease (AD) patients. The results were previously confirmed by quantitative real-time polymerase chain reaction (qRT-PCR) only ex vivo in lymphoblastoid cell lines derived from AD patients and controls. In this study, we compared RGS2 mRNA levels in peripheral blood samples from 69 mild cognitive impairment (MCI) patients to 50 age- and sex-matched non-cognitively impaired controls, out of which 25 patients were monitored at 1 year. We found that RGS2 was indeed downregulated in the peripheral blood of these patients (FR = −1.60, p < 0.001), and despite disease-specific therapy, RGS2 transcript levels continued to decrease at 1 year. The results suggest that RGS2 seems to be involved in AD pathology and progression and can be introduced in a panel of blood AD biomarkers.

Abstract
Background Mental health is affected by both genetic and environmental factors. However, previous studies have showed conflict findings about the role of lifestyle and little is known about the situation of the Chinese population. The purpose of this study was to explore the relationship between the frequency of food consumption, physical exercise condition and mental health, as well as factors related to mental stress in Chinese. Methods We recruited 8160 residents who had health examinations in a public hospital during June 2016 to May 2018. Demographic characteristics, the frequency of food consumption, physical exercise condition and mental health status was collected by a questionnaire. We estimated the association using the odds ratio (OR) and 95% confidence interval (CI) based on Binary or ordinal logistic regression models. A classification and regression tree (CART) demonstrated the prediction of the value of a target variable based on other values. Results The logistic regression model and classification tree model both found that the frequency of fresh vegetables or fruit and fried foods consumption and the current state of drinking alcohol were related to mental stress. The degree of mental stress reduced significantly with increasing consumption of fish (OR = 0.80, 95% CI: 0.71–0.90) and regular exercise (OR = 0.55, 95% CI:0.48–0.64) in females and increased consumption of fish (OR = 0.55, 95% CI: 0.48–0.64) and cereal crop (OR = 0.77, 95% CI: 0.68–0.89), fish (OR = 0.87, 95%CI:0.77–0.96) and regular exercise (OR = 0.61, 95%CI:0.53–0.70) in males. On the contrary, the frequency of consumption of desserts (OR = 1.43, 95% CI: 1.26–1.62) and the current of drinking alcohol (OR = 1.47, 95%CI:1.21–1.79) in females and meat (OR = 1.47, 95%CI: 1.31–1.65), pickled and smoked food (OR = 1.18, 95%CI:1.05–1.32) and the current state of drinking alcohol (OR = 1.25, 95%CI:1.12–1.40) in males were related to an increased risk of mental health. Conclusions Our study showed that both the frequency of some food consumption and physical exercise condition were associated with mental health and affected the degree of stress, which provided novel insights into interventions.

Abstract
Background A variety of DNA-based methods have been applied to identify genetic markers of attention deficit hyperactivity disorder (ADHD), but the connection to RNA-based gene expression has not been fully exploited. Methods Using well defined cohorts of discordant, monozygotic twins from the Michigan State University Twin Registry, and case-controlled ADHD cases in adolescents, the present studies utilized advanced single molecule RNA sequencing to identify expressed changes in whole blood RNA in ADHD. Multiple analytical strategies were employed to narrow differentially expressed RNA targets to a small set of potential biomarkers of ADHD.
Results RNA markers common to both the discordant twin study and case-controlled subjects further narrowed the putative targets, some of which had been previously associated with ADHD at the DNA level. The potential role of several differentially expressed genes, including ABCB5, RGS2, GAK, GIT1 and 3 members of the galactose metabolism pathway (GALE, GALT, GALK1) are substantiated by prior associations to ADHD and by established mechanistic connections to molecular pathways relevant to ADHD and behavioral control. Conclusions The convergence of DNA, RNA, and metabolic data suggests these may be promising targets for diagnostics and therapeutics in ADHD.

Abstract
Depression is one of the most common mental disorders with an increasing incidence. However, factors involved in depression are so complex, thus it is difficult to find effective strategies to reverse the impairments. This study aims to verify the role of regulator of G protein signaling 2 (RGS2) in the mouse mode of unpredictable mild stress-induced depression-like behaviors. Knockdown of RGS2 was achieved by transfection of siRNA-RGS2 in mouse hippocampal (HT-22) cells in vitro and injection of recombinant adenovirus expressing siRNA-RGS2 in mice in vivo. An aberrant high expression of RGS2 was found in mice with depression-like behaviors through immunohistochemical analysis. Silencing of RGS2 or Forskolin (activator of cAMP pathway) developed sweet water consumption, reduced inflammation and oxidative stress injury, and attenuated cognitive impairment and neuronal damage in mice with depression-like behaviors. Furthermore, regeneration was enhanced and apoptosis was repressed in mouse hippocampal neurons in the presence of RGS2 knockdown and Forskolin. Mechanistic studies indicated that silencing of RGS2 promoted the activation of cAMP pathway, thus rescuing depression-like behaviors of mice. Collectively, our study uncovered the role of RGS2-dependent cAMP pathway in regulation of cognitive impairment and hippocampal neuron regeneration in depression-like behaviors of mice, which may be a potential therapeutic target for impairments and symptoms associated with depression.

Abstract
Anxiety and depression are a major health burden. Angiotensin II, via activation of angiotensin II type 1 receptor (AT1R)-mediated brain oxidative stress and inflammation may contribute to these emotional abnormalities. In this study, we investigated the role of a regulator of G-protein signaling 5 (RGS5) protein, which regulates AT1R activity, in angiotensin II-induced brain oxidative stress, inflammation and anxiety-, and depression-like behavior. We hypothesized that deletion of the RGS5 protein would worsen angiotensin II-induced anxiety- and depression-like behavior, cerebral vascular oxidative stress, and brain inflammation. Adult male wild-type and RGS5-deficient mice were implanted with osmotic minipumps delivering either vehicle (saline) or angiotensin II (1 mg/kg/d) for three weeks. Subsequently, mice were tested for locomotor activity, anxiety-like behavior (using the elevated plus maze), and depression-like behavior (using the tail suspension test). After behavioral testing, brain tissue was collected to assess oxidative stress and inflammatory proteins. RGS5 deletion resulted in anxiety-like but not depression-like behavior when compared to wild-type mice. Combined deletion of RGS5 and angiotensin II treatment did not further worsen anxiety-like behavior observed in RGS5-deficient mice. In contrast, depression-like behavior was worsened in RGS5-deficient mice treated with angiotensin II. Interestingly, RGS5 deficiency and angiotensin II treatment had no effect on cerebral vascular oxidative stress, or on expression of the inflammatory marker vascular cell adhesion molecule-1 in the brain. RGS5 deficiency was also associated with decreased blood pressure and an enhanced pressor response to angiotensin II. These data suggest that RGS5 protects against anxiety-like behavior and against angiotensin II-induced depression-like behavior.

Abstract
INTRODUCTION Smoking, anxiety and depression constitute predisposing factors of coronary artery disease. AIM The aim of this study was to investigate the degree of nicotine dependence in coronary patients and its relationship to anxiety and depression. METHODS The study population consisted of 208 coronary patients, 131 men and 77 women, who were hospitalized in a hospital in Attica and were all smokers. The degree of nicotine dependence was measured by the Fagerstrom scale, while depression and anxiety intensity were assessed with the Zung SDS and SAS scales respectively. RESULTS 158 participants (75.9%) were moderately to highly dependent on nicotine, 108 participants (51.9%) reported moderate to severe depression intensity levels while 91 participants (43.8%) reported moderate to severe anxiety intensity levels. The degree of dependence on nicotine was negatively related to the intensity of anxiety and depression experienced by coronary patients. Additionally, the degree of nicotine dependence, anxiety and depression was associated with various sociodemographic and clinical factors such as educational level, social support, and information on their condition and treatment. CONCLUSION Overall, the findings of this study point to an inverse relationship of nicotine dependence, depression and anxiety. However, this paradoxical association could be a product of shared risk factors or confounding. Nonetheless, the development of individualized educational and supportive interventions to quit smoking in coronary patients should primarily focus on the assessment of depression and stress.
